Has anyone without a factory resonator managed to add a cherry bomb or other type of glasspack in between the cat and the muffler? If so, how long is the glasspack and where is it mounted? Does it reduce the available ground clearance?

I've seen the idea discussed here... I took a look under my car and there doesn't seem to be much room for one. My car came without a resonator and I'd like to add one when I mod my exhaust.

using a tape measure, measure the longest straight length of pipe after the cat. If you can fit one in place of the existing pipe then ground clearance wont be a problem, but if you have to reroute it then you might have some trouble.

I was just talking to my exhaust guy about this a couple days ago. There'* room in the intermediate pipe right behind the cat, but if you put in a glasspack as a resonator, he advised to install it BACKWARDS. Better yet, buy a Magnaflow or other major brand resonator. Zero backpressure change, straight flow-thru. I'm either doing that, or going with resonator tips soon.

We've both installed the same flowmaster, he has 2 1/4" tubing with a res, and I have 2 1/2" tubing with no res. Mine was 2x as loud, but not raspy under load at all still. I think a 2 1/4" with no res may get raspy.

Side note, Ol' Blue eye'* with his 3" wide open Magnaflow on a supercharged engine, could not be heard parked next to my car with them both idling...

A Cherry bomb / glass pack will affect the sound, a true resonator will affect sound and quiet it.

Just measured my pipe again, this time more carefully. It is actually 2.5" wide. I thought the SE had 2.25" piping...

Then I measured the straight section after the cat. I measured from the weld right after the cat, to the first point at which it starts bending. It was 13". So I'm off to find a cherry bomb or resonator under 13".

I called around to a few parts stores and let me tell you, those guys really gave me attitude as soon as the words "cherry bomb" came out of my mouth! They immediately assumed I'm a ricer... they don't yet know how I plan to use it.
